Mr Greg Neeld reports
Hawkeye considers the Front Range property to be highly prospective
for diamond-bearing kimberlites or lamproites. The mineral permits
which are in the vicinity of Cadomin, Alberta, exist immediately adjacent
to the Snowbird Tectonic zone, a major crustal lineament that extends
from Baker Lake, NWT to under the Rocky Mountains of central Alberta
near the southern boundary of the mineral permits. Work conducted by
the Alberta Geological Survey indicates that this major crustal structure
has been reactivated during several periods of Phanerozoic tectonic
activity and therefore could easily have provided the deep-seated
pathways that are necessary to allow kimberlitic or lamproitic magma to
ascend to surface. The mineral permits are predominantly underlain by
the Wabamun basement terrane, which is an accreted Proterozoic
terrane that is similar in character and age to the Buffalo Head Terrane.
The Buffalo Head Terrane is the basement terrane that is the underlying
basement to the Buffalo Head Hills kimberlite discovery area. The
Wabamun Terrane may at one point have been attached to or part of the
Buffalo Head Terrane and similarly may also have an Archean
component. Extensive seismic data for the area indicates that the Front
Range property is underlain by more than 50km of crust, likely the
thickest area of crust in Alberta. Anomalous thick crust such as that
which underlies the Front Range property is considered a prerequisite
for the formation and preservation of diamonds in the upper mantle. The
Front Range property is also underlain by a prominent residual gravity
low similar in magnitude to the gravity low that underlies the Buffalo
Head Hills discovery area. This corroborates the seismic data and may
indicate the existence of locally thickened crust beneath the Front Range
property.
Other geological data for the Front Range property indicate that the
property has strong potential for the discovery of kimberlites or
lamproites. This data includes: (1) the property exists approximately
100km northeast of a known diamondiferous lamproite, (2)
diamondiferous diatremes elsewhere in Canada and the world exist in
clusters over large area (in some cases 200km by 150km as illustrated
by the Lac de Gras area, NWT), (3) prior diamond indicator sampling by
industry and government has yielded many high quality diamond
indicator minerals in at least three prominent trends on the property,
such as angular olivine, chromites with favourable diamond inclusion
chemistry, and perioditic and eclogitic garnets and pyroxenes, (4)
diamond indicator minerals recovered from local bedrock sources
indicate that there are possibly two ages of kimberlitic volcanism
evident including intrusions at about 100 Ma and at about 70 Ma, (5)
prior airborne geophysical surveys indicate the presence of numerous
magnetic targets, and (6) the area is underlain predominantly by Lower
Cretaceous to Tertiary sedimentary rocks similar in age and setting to
that which exists at Fort a La Corne, Saskatchewan and the Buffalo Head
Hills and Mountain Lake, Alberta.
At present, the company is reviewing the diamond indicator data in
conjunction with the existing geophysical data including both airborne
geophysics and seismic profile data, in order to prioritize targets on
Hawkeye's Front Range property. Perhaps the single most important tool
for finding kimberlites to date in the Buffalo Head Hills area has been
the correlation of magnetic data with seismic data. Trade seismic data is
available for the Front Range property and will have to be purchased and
reprocessed in order to evaluate the existing geophysical targets.
Hawkeye expects to release the results of this work by early to middle
summer. Several of the properties are in areas of moderate topographic
relief and are amenable to focused fieldwork, including diamond
indicator sampling and ground geophysical surveys, followed by a late
summer or early winter drilling program.
